midu.dev - Cursos de Programación y Desarrollo Web | midudev

Analysis (14 issues)

⚠

Missing image dimensions

Specifying og:image:width and og:image:height helps platforms render your image correctly without delay.

<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />

⚠

Missing twitter:card

Without twitter:card, X/Twitter will use a basic link preview. Use "summary_large_image" for best results.

<meta name="twitter:card" content="summary_large_image" />

⚠

Missing canonical URL

A canonical URL helps prevent duplicate content issues with search engines. Essential for pages accessible via multiple URLs.

<link rel="canonical" href="https://midu.dev" />

⚠

Missing apple-touch-icon

The apple-touch-icon is used when users add your site to their iOS home screen. Without it, iOS takes a screenshot instead, which looks unprofessional.

<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png" />

ℹ

Description is slightly long (188 chars)

Descriptions between 160-200 characters may be truncated on some platforms. Optimal: 110-160 characters.

ℹ

Missing og:image:alt

Adding alt text to your OG image improves accessibility and SEO.

<meta property="og:image:alt" content="Description of the image" />

ℹ

Missing og:site_name

The og:site_name helps platforms identify your brand.

<meta property="og:site_name" content="Your Site Name" />

ℹ

Missing og:locale

The og:locale tag declares the language and region for your content (e.g. en_US, es_ES). This helps platforms display your page to the right audience.

<meta property="og:locale" content="en_US" />

ℹ

Missing twitter:site

Adding your X/Twitter @username helps attribute content to your account and improves brand visibility.

<meta name="twitter:site" content="@yourusername" />

ℹ

Meta description is long (188 chars)

Google typically shows 150-160 characters in search results. Content beyond that will be cut off.

ℹ

Multiple H1 tags found (2)

While not strictly invalid, using multiple H1 tags can dilute the semantic structure. Best practice is one H1 per page that describes the main content.

ℹ

Missing 32x32 favicon

A 32x32 PNG favicon provides crisp icons in browser tabs. Consider also providing an SVG favicon for scalability.

<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png" />

ℹ

No SVG favicon found

SVG favicons scale perfectly at any size and support dark mode via CSS media queries. Modern browsers support them natively.

<link rel="icon" type="image/svg+xml" href="/favicon.svg" />

ℹ

Missing web app manifest

A web app manifest (manifest.json) enables "Add to Home Screen" on Android, defines your app name, icons, and theme. Essential for PWA support.

<link rel="manifest" href="/site.webmanifest" />
